MhlJHINE CQMFFANY, A CGEEQBATIQYH 0Z2" N'EW J 4 TALKING Application filed January 22, "1910, Serial No. 539.594.

To all whom it may cmwctr'n:

Be it known that l; :BICLFORD G. ROYAL, a citizen of the United States, and a resident of the city of Czunden, State of New Jersey, have invented certain new and useful luv proveinents in Telluiig-Mccli1nes, 01% which the following is ii full, clear, and complete disclosure.

My invention relates to that type of sound recording or re ni'oclucing; machines in. which the record support is given a constantly increasing or decreasing angular velocity, in order that that portion of the spirel record groove directly under the stylus oi the recorder or reproducer may he given :1 constunt lineervelocitv, and my invention perticiiilerly relates to the mechanism operating the record support in the manner lrhove referred to.

The object of my invention to construct a sound recording; or reproducing n'nichine which can be interclningeuhiy used to record or L'GPLUtlUC-B sounds from records which are to he rotated at constant angular velocity and from those to he rotutetl at :1 variable angular velocit and which umchine can) be readily and easily controlled and zi'liusted for use with either of said types of )f(.f(')1'(l, to provide it mechanism for varying tl e speed of the motor so as to produce the desired variable speed of the record support which mechanism shall he automatic in its action and independent or" the 1G}IJ1'O(lllCG1 itself; and to provide a device which simple and cosy of n'ninipuletion and adjustment For the purpose of explaining the manner in which my invention may he carried out in practice, i have shown in the drawings 21 sound reproducing machine provided with my means for operating; the same With both types of records above referred to, out my invention is not to be construed as being liinited to a sound reproducing machine as it is equally in: ipteihle foruse in recording niachines. I

in talking machines or sound reproducing machines of the type in which the record is in the form of a disk, having therein n spiral roove the convolutions of which he in at or near the periphery of the disk and terminate at a point near the center of the dish, and in which during the reproduction of sound therefrom the reprodijzcer is carried ine'ertilv from the periphery oi the dish toward the center, by reason or the engagement of the Specification of Letters Patent.

stylus with the record groove), it is apparent that, with e fixed en 'uler velocity of the record support, the linear velocity of each. convolution will decrease in 2], fixed ratio from the outer to the inner convolution of the record groove and the invention of this application then relates to the roviding of; a mechanism, whereby the speed of the rec-- orcl as it moves under the stylus uniy he mode constant at the point oiits engagement with the shins and to do this the :i echenisin described below is provided to counteract the decrease in the linear velocity of the groove by importing to the record support ii constantly increasing angular velocity, and the rate oi? the increase in speed slmuld he in vcrscly pri'ipor 'ionul to the proportion which the radii of adjacent convolutions oi the spiral hear to each other for each revolution. of the record support; that is to suv by "Way cl? exmnple, when the reprorluce hes traveled across the record one-hail oi? the dis" tuncc froin the periphery of the disk and the center of the disk or record, the speed should be increased two times to nu-ziinteiu :2 constunt linear speed under the stylus proportiouull throughout the whole oi": the re 'iroducer across the record. is a. 'coinplished by the cum indepe: the reproducer and d mechanism as will he described helow.

it is obvious that to correctly reproduce the sound from 2t record in which the record support, and conseqiusntly the record mount ed thereon, will have this variable speed in ported to it, it will have been necessary to have made the original record upon it cording machine to the support of the curface being recorded of which was imparted n corresponding variable angular velocity.

My invention has for one of its objects the providing of a talking machine with a mechanism which will enable it to he used with either style of record; that is to sage with. records in which the record wee orig;- iimll v recorded upon at disk which was revolved at e constant angular velocity, and one in which. the record was originally re corded upon it record having: 2L vuriel'ile angular velocity, the variation being; such as .uleut A en by the motor l to import :1 constant linear motion to the in the drewin' forming or part of this specification, and in which like reference all) ' shaft 19, journaled in suitable bearings characters are used to designate the same parts through various views, Figure 1 is a side elevation of. a recording driving mechanism embodying my invention and shown as mounted within a sound-reproducing machine cabinet, which cabinet is shown in section; Fig. 2 is a bottom line view of-the same; lfig. 3 is an elevational sectional view of the mechanism shown in Figs. 1 and 2, the said section being taken on the line lllll---lll of Fig. 2; Fig.4. is a similar sectional elevational view taken. from the line lV-lV of and Fig. 5 is a sectional view of a portion of my device taken from the line VQV of Fig. 2.

lieferrimenow more particularly tod igs. 1 and 2, a motor cabinet 1 may be provided with a top lid or closure 2, from which is suspended a plate 3, upon which the various parts of the motor are mounted, which motor may consist of the usual spring barrel 4, operatively connected to the winding-shaft 5, supported in the bearing-blocks 67, mounted upon the plate 3. The windingshaft 5, may extend, as is usual, to a point adjacent to the opening 8, in the casing 1, for the attachment of a winding crank thereto. The barrel elmay' be mounted in the h urineblocks (3 and 6 or in any other convenient manner.

Connected in any suitable manner With the spring barrel his a gear 9, which meshes with a pinion 1.0, on the shaft 11, journaled at one end in said bearing-block 6, and on its opposite end in a bearing-block 12, suspended from the plate 3. The shaft 11 also carries a beveled gear 1.3, meshing with a beveled pinion 1a, rigidly connected to the spindle 15, to the top of which is secured'a record-support-lti. The spindle 15 is also provided with a worm-gear 17, which meshes with and drives a worm 18, on the governor- 2l, said governor-shaft being provided with the usual fiyballs 22 mounted onsprings 23, the ends of said springs being connected respectivz-ily to the cellars 24. on the gov ernor-shaft 19-. As is usual in this type of governor the collar 24: is rigidly secured to the governor-shaft it while the collar 25 loose on the said governor-shaft and is connected to a governor-disk or plate 26, which, by the centrifugal action of the flyballs, is drawn inwardly when the balls rotate, the extent of movement being dependent upon the speed of the rotation of the balls. The spring 27 tends to counterbalance to the desired extent the tendency of the collar 25, and the disk or plate 26 to Hui-2'2 inwardly under the action .of the said liybails.

a The mechanism for varying the speed.

of the motor is as follows Meshing with the pinion it), is a gear 28, 2a,; secured to a. shaft 23), mounted in bear-r )loc-ks 30----3] which may be secured to the plate 3 in any suitable manner. The shaft 29 is also provided with a worm 32, which in turn meshes with a worm-wheel 33, mounted on a shaft 34, which in turn may be manually moved longitudinally in a bearing-block 35, mount-- ed on the plate 3, The shaft 34 has also rig idly secured thereto a cam 36, and the said shaft has an outer bearing 37, which bear- 1 ing is provided with a. dial 38, stationarily 75 secured to said bearing 37. The end of the shaft 3% is provided with a knurled head 39, cz'irrying a pointer elO, said head and pointer being rigidly secured to said shaiitB l, and the pointer being adapted to swing over and around the dlal 38 when the shaft is drawn outwardly to the position indicated in dotted lines in Fig. 2, and manually'turned, by means of the knurled head 39. i As has been previously stated, the shaft 34 is longitudinally movable in its bearings, the extent of the movement being sufiicient to move the worm-wheel 33 into and out of engagement with the worm 32, as is plainly indicated in Fig. 2. To hold the shaft 34 in position-that is to say, so that the worm 32 and the worm-wheel 33 are in engage ment, a suitable lock may be provided, such is shown in Fig. 5. In this case the shaft 34% is provided with a groove, 41, while the bearing block 35 is provided with a suitable opening registered with said groove and through which a pin, 42, extends, the end of said pin fitting within the said groove 41 and being normally held in that position by 100 a leaf-spring 43. It will be seen, then, that when the knurled head 39 is grasped and the shaft is forced longitudinally inwardly so that the worm 32 and the worm-wheel 33 engage, said shaft and the parts connected 1i)5 thereto are locked or retained in that position. To bring said worm and worm-wheel out of operative relation, it is m'erel necessary to draw the knurled head 39, Fig. 1) outwardly, thereby slipping the groove 11. out from under the pin 42. i

Mounted upon a suitable standard, 44, is a lever, 45, the free end of which rests against the surface of the cam 36, and mounted upon the same standard and adjacent to said lever 45 is a brake lever 4-6. This brake lever 46 extends inwardly to a position adjacent the inner side of the governor-disk or plate 26, and is provided with a suitable pad 47, adapted toengage the said disk or plate 26. The opposite end of said lever is provided with a screw, 4-8, or other suitable adjusting means, the end of the screw being threaded through the said brake lever 46 and bearing against the letter 45, the end of the screw being. held in engagement with the said lever 45 by means of a spring 4-9, one end of which is at tar-lied to said brake lever 46, and the other I end of which may be attached to any suit- 13c lar speed of the record support would he decreased instead of increased, but this reversal of the parts and operation is fully within the aim and scope of my invention and Will not depart from my invention abo'vedescribed or vary substantially the operation of the mechanism.

Although in my specification and cla ms I have termed the record upon which the sound. was recorded as a disk record, ll employ this term for the purpose of indicating broadly any type of record in which the sounds are recorded in a line, or ridge or groove in spiral form, that is to say one in which the record line, ridge or groove begins either'a't the outer periphery of the disk and extends in. a spiral toward the center of the disk or conversely one in Which the record begins at or near the center of the disk and the line, ridge or groove extends out wardly in a spiral form to or near theperiphery of the. disk and the stylus may be either a recording or a reproducing stylus.
